HeLp! 4.3e Wii softmod

Hi,
A while ago I had the twilight hack done on my Wii, then what I did was accepted the update from Nintendo because I lost the excitement in messing around with the Wii bringing me to 4.3e and that was the end of it. Everything like my Homebrew Channel had been wiped and Neogamma and all the rest and it was just your standard wii. I see that Wii hacks have come a long way since then and am now deciding to redo it. This time with the letterbomb exploit. I want to be able to run games from a hdd and I need quite a bit of help. I have seen people mention things like WFBS and CIOS... You know, all the jargon and all what I need to do it with, truth is, I don't understand any of that. I need to know quite a few things:

What IOS things do I need

Can you recommend a hdd for the Wii that is extremely compatible with usb loaders and stuff and can be bought from a UK website now (I'd appreciate it if you didn't send me to the GBATemp compatibility list as the hdd's there are only amazon.com based if you understand what I mean as I am in the UK)

Could you just condense all of the jargon into a quick and simple way of doing it

I just want to be able to run backups on a decent hdd that doesn't crash after the first five minutes

What else would be handy is if I new how to rip GC games aswell

Sorry if the post is in the wrong section of the forum or anything like that. I'm not very good at all this forum business
I have tried sifting through the forum and stuff but I get lost in all of the jargon, you see, some people just expect you to know what they're talking about and I don't.
